Abstract: PROBLEM TO BE SOLVED: To improve a followup property of a valve by reducing response time in the case that pressured water in a main valve cylinder chamber is made to flow to the secondary side and secondary pressure of a main valve is adjusted to a prescribed value. SOLUTION: A valve is changed over interlockingly with displacement of a diaphragm due to balance of force of a spring 60, and force of secondary pressure introduced from a pilot port PL. A primary pressure port P1 is communicated with a cylinder port CL for supplying primary pressure to a first cylinder chamber 18 at a left-side changeover position where the secondary pressure is lower than a prescribed value. A main valve 10 is thus opened to increase the second pressure to the prescribed value.

The cylinder port CL is communicated with a secondary pressure port P2.  Pressured water in the first cylinder chamber 18 is made to flow to the side of the main valve 2, for closing a valve 24 and decreasing the secondary pressure to the prescribed pressure.

Filed: 1987-11-25
Abstract: PURPOSE:To simplify the constitution with high accuracy by projecting coherent light on a Fraunhofer hologram formed of radial gratings fitted to a rotary body, and arranging photoelectric converters at the position of its reproduced image. CONSTITUTION:The reflection type Fraunhofer hologram Hr is fitted to the rotary body 1 and rotates in one body. Light emitted by a laser light source LS is incident on the Hr through an optical system. The incident luminous flux is diffracted and reflected to enter a convex lens 4, thereby forming the reproduced image of the Hr on the focal plane at the position of the focal length f1 of the lens 4. The position of the reproduced image does not shift even if the position relation between the Hr and lens 6 changes, so the photoelectric converters 5 and 6 are arranged there to obtain the reproduced image at all times. The reproduced image has a pattern similar to that of the radial gratings of a body used to form the Hr, so index slits are provided at specific positions on the photodetection surfaces of the converters 5 and 6 and then output pulses from the converters 5 and 6 are processed to obtain information on the direction and quantity of rotation.

A displacement sensor 7 which detects the distance to the displacement detection part 15 is fixed to the base 4. The displacement sensor 7 directly detects the displacement amount of the piston 3, according to the distance to the displacement detection part 15, so that the displacement detection precision of the piston 3 is high.  A voltage is applied to the piezoelectric displacement part 2 from a control equipment, in the manner in which the detection value of the displacement sensor 7 becomes equal to an aimed value. Thereby the displacement amount of the piston 3 can be controlled with high precision, independently of the hysteresis which the piezoelectric displacement part 2 has.
